Answer:
a). Yes. Area will be less than 100 square in.
b). Area of octagon = 82 in²
Step-by-step explanation:
From the picture attached,
a). Octagon is inscribed in a square having one side = 10 inches.
Since, octagon is obtained by cutting off the four equal corners of the square,
Area of octagon will be less than the area of the square.
Area of square = (side)²
= 10²
= 100 in²
Therefore, area of octagon will be less than 100 in²
b). Since, corner cut off from the square are equal in shape and area,
Area of one corner (right angle triangle) =
=
= 4.5 in²
Area of 4 corners = 4.5 × 4 = 18 in²
Area of octagon = Area of square - Area of 4 corners removed
= 100 - 18
= 82 in²
The answer is $143.70
(Work is below)
First calculate sales tax by multiplying $124.95 x 0.07 -
Model Rocket Kit: $124.95
Sales Tax Rate: $ 0.07
x__________
$ 8.7465
You round up because ^ more than five (four or below you would round down)
Sales Tax: $8.75
Then you add the sales tax to the model rocket and add the shipping.
Model Rocket Kit: $124.95
Sales Tax: $ 8.75
Shipping $ 10.00
